To @Hw/710m t may concern Be it known that I. ABRAHAM S; Krasnxnn, a citizen of the United States of America, and a resident of ljhiladelphia, in the county orn Philadelphia and Statefoi Pennsylvania, have invented certain new and useful lmprovements in Machines for Extracting Oils, oi' which the following' isa speciiication.

This invention relates to improvements in machines adapted for expressing oilA fromv seed, and it is intended particularly for use with cotton seed, but it willbe obvious that the use is not confined to this purpose.

rlhe invention consists in the machine shown in its preferable but not necessary embodiment in the accompanyingY drawings and as hereinafter described and claimed.

In the aforesaid drawings: Figure 1 is a vertical central section oi" a machine made in accordance with my invention. Fig. 2. is a top plan view with parts broken away.

Fig. 3 is a horizontal section on theline 8 3- oi Fig. 1. Fig. l is a section on an enlarged scale through one of the compressing devices and its coperating parts. Fig. 5. isa detail on a muchV enlarged scale, partly in section, showing: the under side of the structure shown in Fig. 4. Fig. 5a is a perspec- ,Y

tive view of one of the details shown in; Fig. Fig. 6 is a sectional view showing the device for operating the valves. Fig. 7 is a detail of the valve operating' mechanism. Fig. S is a perspective view of the cams and valve operating mechanism. Fig. 9 isa vertical section ofy one of the Ina-in plates and adjacent parts slightly moved out of their normal positions. Fig. 10 is a detail,

partly in section, of one of the centrifugal 53. .is a side elevation ofY the plate shaft; having. a. pulley 2 thereon which, may be drivenby anordinary belt 4r. The shai't 1f. is vertically disposed and, linds a bearing in. a. main frame 5 which extends laterally from saidV shaft' and from which projects upwardly verticali frame members 6, which in. turn. have horizontal members 8 meeting atthe center in the form of a bearing 10, as clearly seenin Figs. 1 and 2. This bearing 10y affords an upper support for thetop of the shaft 1 and its surrounding parts herein.- after described. The fouruprights 6 are connected together. by curved frame members. 12, as shown in Fig. 2, and it will be understoodthatf the horizontal frame 5, the aforesaiduprights 6,. the horizontal members, S, the central bearing l0 and the curved segmental frame'members 12 are all fixtures and that`4 the.- shaft 1 and the, other parts hereinafter referred to rotateA within the space inclosed by said members. From, the horizontal :trame` 5- depends an arm la having. a. bearing` 16, and inthis bearing and another bearingv 18V is, journaled a supplemental shaft. 20., Thisshaiit 2O has fixed toit a` gear 22 meshingfwith and receiving motion from. a gear 24.. fixed to the main shaftl.

To the upper end of the` supplemental shaftQO are secured'two gears26 and 28, the i gear 26. meshing with a, gear which is keyed to a.sleeve.32 journaled upon the vertical shaftlV The other gear 28, keyed to the. supplemental shaft 2.0, mesheswith a gear 3.4 which is journaled upon the aforesaidsleeve 32 and'this gear 34 has keyed to itthe camwheel. Thev gear 28 is slightly smaller thanA the` gear 26 and consequently thev gear 3i anditscam wheel 36 are driven ata slightly lower speed than the gear 30 and the sleeve. 32, so that the sleeve 32 progresses in its, rotary movement with respect to the cam wheel 36 for a purpose to be hereinaft'erdescribed. A. circular plate 40 is secured to` the sleeve 32 and some distance above this circular plate 40 is ay similar plate 12. These plates 40 and 4:2 each hasfa centralopening for the shaft 1 and in addition saidfplatesare provided with concentric openings, as hereinafter described, said openings' being preferably arranged in series of ten. The outer series often openings are to receive vertical rods 44 upon weights 52 sov that, when the plates 40 and 42 are rotated at great speed, centrifugal action of the weights 52 will force the com-,

pression blocks 46 outward within the spaces of the drums 48, the centrifugal weights 52 being pivoted at 54 (see Fig. 2). Each of the drums 48 is provided on its exterior with a gear 56 and this gear meshes with a small gear 58 journaled upon a stud shaft 60 and meshing with a gear clutch 62 upon Va shaft 64. It will be understood that there are ten shafts 64 and it will be seen that these shafts are journaled in the inner series of openings in the plates 40 and 42 and, as said plates are rotated with respect tothe main shaft 1, said shafts 64 are rotated owing to the fact that gears 66, keyed to said shafts 64, mesh with a gear 68 keyed to the main shaft 1. Each of the shafts 64 has keyed thereto an upper clutch member 70 and if these clutch members were constantly in engagement with the aforesaid clutch member 62, then the drums 48 would be constantly rotated, but the upper clutch members 70 are provided with forked levers 72 which in turn are provided with `spring actuated plungers 74 acting to normally hold the clutch levers with the clutches in the open position shown in Fig. 1 so that the drums 48 cannot be rotated unless the forked levers are operated to make one of the clutch members 62 engage its complemental clutch member 70. To bring these clutches into engagement at the proper time, the aforesaid cam wheel 36 is provided with an annular. cam iiange 76, this flange being provided with two depressions 78 (see Fig. 8)

which, as the cam is rotated so as tobring either of said depressions under the aforesaid plungers 74, permits the spring of the appropriate plunger to force the plunger downward so as to bring the two clutch members 70 and 62 into engagement, and as long as the clutching engagement continues, motion is transmitted from the gear 68 through the gears 66, 62 to the gear 58 and from that gear to' the gear 56 and its drum 48. Depressions'78 in the cam flange 7 6 are of sul'licient length to maintain the clutch members 70 and 62 in engagement for a period sufficient to rotate the appropriate drum 48 180, at which time the flange at the other end of the depression operates to thrust the rod upward against the tension of its spring to break the clutch 70, 62. The reason the short depressions 7 8 permit any of the plungers 74 to be depressedby its` spring a sufficient length of time to rotate its .has a compression block 46 working therein which areV of the shape shown in horizontal section in Fig. 8 and are capable of movement back and forth. In other words, each of the compression blocks 46 has two fiat sides connected by .curved ends, and the drums 48 have their interiors also formed with two fiat sides connected by two curved ends, so that each flat sided compression block 46 fits within the flat sided interior of its drum 48. However, the curved ends of the interior of each drum are farther apart than the length of the compression blocks 46 so that the compression blocks are capable of movement withinthe drums, the flat sides of the compression blocks sliding within the flat sides of the drum. The curved interior walls of the drums 48 are provided with perforated steel platesL 80 (see Figs. 4, 15, 16 and 17) and each of these plates has a facing of camels hair 82 secured thereto by means of rivets 84, a securing plate 86 being employed at the top and bottom to more securely hold the camels hair in position. The interior of the drums 48, behind the curved perforated plates 80, are provided with vertical grooves 8 8, the construction being such that when the compression blocks 46 are forced outward against the camels hair covering, as indicated at the left of Fig. 4, the oil is eX- pressed from the seed and passes through the camels hair, through the Vopenings in the plate 82, into the vertical grooves 88 and from thence the oil drops by gravity vinto andthrough tubes 90 shown in Figs. 1

Fig. 4, showsl one-of the compression blocks 46 at its eXtreme compressing point with a cake of compressed seed under the action of its vcentrifugal weight 52, and with a charge being fed in at the right hand side of the compression block in a manner to be hereinafter described. Figs. 13 and 14 show in diagrammatic views the action of the compression blocks; Fig. 13 showing one of the centrifugal weights 52 still' in the act of compressing the seed at the place indicated at a; the space marked b having been filled with a new charge. Further rotation of the drum 48 from the position shown in Fig. 13 will draw inward its weight 52 against centrifugal force, unt-il the straight interior walls of the drum 48 are in the position shown in Fig. 14 when the links 50 connecting the compression blocks 46 with the weight 52 will be in such a position that, centrifugal force acting upon the weight 52, will cause said links 50 to draw the compression blocks downward from the point shown in Fig. 14 in order to compress the charge which has been previously fed into the opening Z).

Various mechanisms are provided in order to inject a fresh supply of material into the drums 48 prior to compression, also` to eject the material after compression, and in addition, a gate has to be opened in order that compressed material may be ejected, and of course said gate has to be closedfafter ejection in order to be ready to receive a new charge.

l will now describe the various mechanisms for supplying material, opening the gate, for ejecting material, and for closing the gate.

4s shown in Figs. 1 and 4, at one period of movement of the drums 48, the open space Z9 referred to in Figs. 13 and 14 is immediately under two ports and 102, the first of which is for feeding material to the opening, and the other for injecting a blast of air to eject the compressed cake. The port 100 is in communication with a port 104 which leads to a valve chamber contain ing a valve 106. On the other side of the valve is a port 108 communicating with a large chamber 110 formed between two plates 112 and 114 located upon the upper side of the large revolving plate 42. This large chamber 110 is constantly in communication with a central feed opening116 in the main shaft 1, radial passages-118 being provided whereby material may be fed under pressure from the central passage 116 to the large chamber 110. It will be understood that 'when the valve 106 is in the open position shown in Figs. 1 and 4, the material under pressure will pass through said valve, through the ports 104 and 100 and into the drum 48. rit the appropriate time, the valve 106 is turned to shut olf the supply of material. rPhe other port 102, hereinbefore referred to, is arranged to feed a blast of air, and in order to control the air a valve 120 is provided, and a pipe 122 leading from this valve to an annular chamber 123 in the upper plate 114 hereinbefore described. This plate 114 is provided with a hub 124 which is formed with vertical passages 126 leading to a radial passage 128 provided with an air supply pipe 130. It follows from this construction that when the air valve 120 is in the open position, a blast of air will be fed thro-ugh the pipe 130 and its connecting openings into the chamber within the drum, to expel the compressed charge. However, before the charge can be ejected a gate at the bottom end of the compression blocki must be opened. Such a gate lis designated 130 and is shown in Figs. 1 and 4. This gate is arranged to slide radially at the appointed time, and to that endvis provided on its lower side with a roller 132 which rideswithin a cam groove 134 on the face of the main cam 36 (see Figs. 4 and 8). This cam groove 134 is provided with two sets of projections 136 and complemental recesses 138. When the roller 132 enters one side of the recess 138 the gate is withdrawn and held withdrawn until the roller leaves the other side of the recess 138 when the gate is automatically closed in a manner easily understood from Fig. 8.

The opening in the bottom plate 40 (see Figs. 4 and 9) is provided with an annular ller 140 shown in position in Fig. 4 and illustrated out of position in Fig. 9, this filler having a downwardly projecting apron 142 against which the gate 130 hereinbefore referred to closes, as seen in Fig. 4. This apron 142 of course rotates with the plate 40, and when the gate 130 is opened, the cake is ejected from its drum,l and the apron 142 guides the cake downward through the open ing near the framework where it may enter a suitable bin (not shown) it being understood of course that if it were not for this apron 142, centrifugal force acting upon the cake,v as it is ejected, would tend to throw the cake outward. l might here mention the fact that the framework is formed with an. upwardly projecting circular plate 144 which forms additional means of preventing any material from escaping laterally.

1n order to operate the valves 106 and 120 at the appropriate times, l employ vertically disposed valve operating rods shown best in Figs. 6, 7 and 8. Each of these rods 150 is intended to open and close both valves and'to that end its lower end is provided with a cam. roller 152.` which enters the cam groove 154 in the periphery of the aforesaid main ca1n136. The upper end of the valve rod is providedv with a rack 156 which meshes with a pinion 158 projecting fromthe stem of the feed valve 106 (see Fig. 7 It will be obvious that the up and down movement of the valve rod 150, through the rack 156 and the gear 158, will rotate the feed valve 106 to open and close the same. Immediately at the rear of the pinion 158, and movable therewith, is a. cam 160. This cam 160 is provided with a cam groove 162 iaving -a hump 164 thereon, as indicated particularlyin Figs. 6 and 12. The valve 120, before mentioned, has a short crank arm 166projecting therefrom which is pivotally connected by means of a link 168 with a cam arm 170 pivotally connected to the valve frame at 172.'V This cam arm 170-has a cam roller 17.4 which fits within theV groove 162 in the cam 160. The construction is such -that when the cam roller 174 is'on top of the hump 164, as illustrated in Figs. 6 and 12, the valve 120 is in the open position shown in dotted lines in Fig. 6 in order that a blast of air may pass through the valve 120 and eject the cage as will be hereinafter described. The construction so far described is such that if the valve operating rod 150 is moved upward slightly, it rotates the gear 158 in a clockwise direction very slightly, suflicient however to cause the cam roller 174 to move up on top of the hump 164, thus acting upon the cam arm 170 and the link 168 to open the valve 120. If the vertically operating valve rod 150 is then moved downward, the gear 158 is r0- tated backward to permit the cam roller 174 to be moved downward off of its hump 164 when the air valve 120 will be closed. Further downward movement of the valve rod 150 will continue the rotation of the gear 158 but during the further rotation, the cam roller 174 remains inactive, as the cam groove permits the cam to be moved to the left in Fig. 6 without further radial or upward movement of the cam roller 174. But this further rotary movement of the gear 158 acts to rotate the feed valve 106 suificiently to bring the same to the open position shown in Figs. 1 and 4.

1 will now refer once more to the main cam 36 in order to show how the vertically operating rod 150 is given the peculiar movements before referred to in order to open and close the air valve at the proper time and then to open and close the feed valve. It will be recalled that the gear 34 and its cam wheel 36 rotate at a slightly lower speed than the gear 30, its sleeve 32 and the plates 40 and 42, so that the plates 40 and 42 overtake at a very low rate of speed the main cam 36. All of the vertically operating valve rods 150, one of whichy is shown in Fig. 8, rotate with the plates 40 and 42 and therefore these valve rods also slightly overtake the projections in the peripheral cam groove 154. By referring to Fig. 8, it will be seen that this cam groove is provided with a hump 180 so that as the plates 40 and 42 and the valve rods 150 overtake this hump 180, the appropriate valve operating rod 150 is given the slight upward movement hereinbefore referred to which rotates the gear 158 in a clockwise direction to move the hump 164 under the cam roller 174 and thereby open the air valve 120. Thus a blast of air is admitted through the valve to eject the cake from the right hand side of the drum 48, shown in Fig. 1.` As the parts continue to rotate, the plates 40 and 42 and the particular valve rod 150 which has just been elevated by the humpV 180 now pass beyond said lump onto the level portion 182, thus causing the valve rod 150 to descend to close the air valve 120. The air valve and the feed valve are now both closed and remain closed until the cam roller 152 on the valve rod 150 progresses with respect to the cam 36 until the cam drops from the level portion 182 down into the deep. recess 184, shown best in Fig. 8. This causes the valve rod 150 to drop down sufficiently to rotate the gear 158 far enough to open the feed valve 106 and admit a new charge into the appropriate drum 48. The feed valve remains open for the length of the deep recess 184 but when the valve rod 150 progresses far enough to ride up at the end of this recess, said valve rod 100 will be again elevated until it reaches the normal height of the cam groove 154, shown in Fig. 8, when the feed valve 160 will be closed. From this point, both the air valve 120 and the feed valve 106 will be closed until this particular valve rod makes one-half revolution with respect to the main cam 86 to overtake the hump 180 on the opposite side of the cam, when it will be understood that the operations of both valves will be repeated.

Fig. 12 shows in diagrammatic form the valves and the cam grooves 154 just described. In this figure the cam roller 152 is shown on top of its hump 180 so that the rack 156 has been elevated slightly to move the gear 158 in the'direction shown by the arrow over said gear in said Fig. 12. At this point the valve 120 is shown open, as illustrated in dotted lines, connected by the double headed full line arrowl a, shown in full lines, connecting the cam roller 152 with the valve 120. Two other double headed full line arrows Z) and c indicate respectively the upper position of the rack 156 and the valve orifice of the valve 106 in a vertical position, whereby the feed valve 106 is closed. Now it will be understood from this Fig. 12 that when the roller 152 moves in the directionY of the short arrows, indicated in the cam groove 154, the roller 152 will be caused to descend to the level 182 and as the cam roller 152 continues its further move-l ment, it will descend farther to the position shown at 184. The position of the parts when the cam roller 152 is shown in dot and dash lines in the deep recess 184, Fig. 12, is illustrated in dot and dash lines in this figure. By referring to the double headed dot and dash arrows, d, e and f, it will be noticed that the air valve 120 is shown closed; the arrow e represents the rack in its lowest position so that the valves are indicated at the arrow 7" as horizontal and therefore with the feed open. At this same point, the cam 160 is moved around to the point illustrated by the dotted arrow g and by the dot and dash lines in Fig. 12. When the cam roller 152 is again elevatedto the position shown by the arrow 7i at the eXtreme right of Fig. 12,

the valve operating rod 150 has been elevated to its normal level with both the air valve 120'and the feed valve 106 closed.

Fig. 11 shows in diagrammatic form the cam 36 with its various cam rollers. The upper roller 152 represents the roller just described for raising and lowering the valve operating rod 150 to open and close the air valve and to open and close the feed valve. The roller 132 is the roller for opening and closing the gate 130. The roller 75 is the roller for moving the plunger 74 to operate the clutch 70.

Having in mind the diagrammatic form shown in Fig. 11 and the fact that, as before stated, it takes twenty-four hundred revolutions of the plates 40 and 42 and their connected parts to gain one revolution upon the main cam 36, shown in diagrammatic view in said Fig. 11, the operation of my machine is as follows: Vile will assume that the parts are operating at great speed and that the tendency of the weights 52 is therefore to be thrown outwaid on their pivots 54 in order to compress any inaterialwhich may be between the plungers 46 andthe drums 48. 'lalring Fig. 4 as an example, it will be seen that the feed valve 106 is open, and therefore the supply of material is forced under pressure through the port 104 into the open space at the right hand of the compression block it this time the roller 152 is at the lowest part 184 of its cam groove and the roller 132 is at the high part of its cam groove so that the slide 130 is closed. rlherefore, the material is fed into the drum 48 as long as the valve 106 is open, or until it is full, and as the rollers 152, 132 and 'a' 5 progress with respect to the cam 36, the roller will ride out of it recess 184, thus closing the feed va` ve 106. Further progression of said rollers will bring the roller 75 into its recess Z8 so as to bring the clutches 70 and into active engagement, thus causing the gears 02 and 58 to rotate the external gear 56 on the drum 48, in order to turn the drinn and its compression bloclr 46 on their axis. rllie length of the recess 7 8 is justl suilicient to hold the clutch in engagement long enough to rotate the drum and its compression bloclr 180O in order to bring the charge from the right hand side of the drum in Fig. 4 to the left hand side in order that centrifugal f ree acting upon the weight 52 may cause' the compression block 46 to squeeze the charge against the plate 80, thus expressing the oil therefrom which, passing through the perforatioiis in said plate 80, enters the vertical grooves 88, and drops from thence into the tubes 90 and into the well beneath said tubes. It will be recalled that it takes twenty-four hundred revolutions of the plates 40 and42 and their connected parts to gain one lap on the main .cam

and, as the cam has its actingparts diametrically opposite each other, as illustrated in Fig. 11, it follows that the material in the drinn 48 will be under compression for onehalf of the period that it takes the plates 40 and 42 and their connected parts to gain one lap on the main cam 36. Therefore, the material is under compression for the length of time that it takes the main shaft and the plates 40 and 42 and their drums to rotate twelve hundred times. However, during part of this time, it is necessary to eject the cake which has previously been compressed in 4the drum 48 and we will now again refer to Figs. 4 and 11. As soon as the drum 48 was rotated 180O to put its fresh charge under the influence of thel compression block 46, the cake shown at the left hand side of Fig. 4 was brought around to the right hand side. As soonas the centrifugal force draws the compression block 46 to the left, it would tend to leave the space between the block and the perforated curved plate 80. We must remember, however, that centrifugal foice is jalso acting upon the cake which is against this plate 8O and therefore the action of cen trifugal force pulls the compressed cake away from said plate 80 and forces it against the right hand wall of the compression bloclr 46, as viewed in Fig. 4, where it will be immediately under the air oriiice 102. N ow, by the time the charge on the other side of the block has been almost entirely compressed, the cam rollers 152, 132 and 75, illustrated at the top of Fig. 11, will overtake the main cam 36 and have reached the positions shown at the bottom of said Fig. 11. it this time the roller 132 eriters its recess 134 at the bottom of Fig 1, thus causingrthe slide 130 to move to e right as viewed in Fig. 4, opening the sp :.ce under tne opening in the drum 48 in order that the compressed charge may be expelled. At this time, as before stated,-the charge just previously compressed is under the air oritice 102 and as the roller 152 rides upon the hump 180, shown at the bottom of Fig. 11, the valve operating rod 150 is elevated, as hereinbefore described, ust sufiicient to open the air valve 120, thus permitting a blast of air to be forced upon the upper edge of the compressed cake, thereby expelling Ythe same from the opening in the drum 48 out of the bottom thereof, the slide 130 being still open as previously described. Continued rotation of the rollers 152, 132 and 75 brings the roller 152 over its huing d baclr to the level 182, shown at the bestem of Fig. 11, so that the air valve now closes, and as sail .rollers still progress with respect to the cam 36, they roller 132 rides out of its recess 134, thus again closing the slide 130. Now as the rollers progress still farther, the roller 152 ridesinto its deep recess 184, shown near the bottom of Fig. 11 and in the diagrammatic view of Fig. 12, thereby opening the main feed valve 10G in order that a new charge may be forced into the opening in the drum 48. Continued progression of said rollers will cause the roller 152 to ride out of its recess 184, thus closing the feed valve and then as the roller 7 5 rides into its recess T 8, the clutch 69.- is again closed to again rotate the drum 48 1800, when the operation just described is again repeated.

It will of course be understood that the operation just described with respect to one of the drums 48 is the operation repeated by all of the ten drums as they rotate with respect to the main cam 3G.

It is obvious that modifications and variations may be made in my invention without departing Afrom the spirit thereof and reference should therefore be made to the appended claims to determine the scope ofthe invention.
